I faced a lot of obstacles when working on the assignment. One of them is the section of the roof due to the complexity of it. Other than that, the placement of the internal spaces, openings, and furniture are needed to be arranged logically, therefore I have to consider it carefully when planning it. One fun fact that I learned from this assignment is that normally, the height of the window will not be constructed all the way from ceiling to the floor level. A small drop on the floor will also be constructed when entering bathroom to prevent water from overflowing.
